This inr'entionrelates to power devices and more particularly to a transmission structure especially designed for transmitting power from a drive shaft to a driven shaft.

The primary object of the invention is to provide novel means for reversing the direction-of rotation of the driven shaft in such a manner as to eliminate the necessity of stopping the power device in order to accomplish the reversing of the driven shaft.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination and arrangement of parts and in thel details of lconstruction hereinafter described and claimed, it being understood Y that changes in the precise embodiment of the invention yherein disclosed, may be made within the scope ofwhat is claimed', without departing from the spiritof the invention.

Referring to the drawings;

Figure 1 is a side elevational view of aA power device constructed in accordancewith the invention, parts thereof being show-n in section.

lFigure 2 is a sectional view taken on line 2-,2 of Figure 1.

Figure 3 is a plan view of the brake con; trolling carriage. Y

Figure 4 is a sectional view taken on line 4 4 of Figure 1.

Figure 5 is-a sectional viewv taken on line l 5-5 of Figure 1.

Referring to the drawings in detail, the reference Icharacter 5 designates the support- 'ing shaft of the power device wl'iich'is mounted in bearings 6 disposed .in the upper end of the support 7, the opposite end the shaft being mounted'in a suitable support not shown.

rIhe motor or power element, forms no part of the present invention, however a portion of the power element is shown, and indicated by the refeience character 8, the same being keyed to the shaft 5 to cause the shaft to rotate with the power element. i

The shaft 9 is formed with a fiange'lO to which the ring gear 1 1 is secured by means.

tances apart, the linner ends of the shafts being mounted in openings formed.' in the. bearing 17. The drivenl shaft is indicated. at 13 and is also mounted `on the bearings 19 that are positioned on the shaft 5,' the driven shaft being'provided` witha flange 2()` at one end thereof to support the ring gear 21, the ring gear being secured'by meansof bolts v i The teeth of the ring gear 21 also `cooperate with the teeth of the pinions 13 'sothat movement of the hollow shaft 9 may, be directed tothe shaft 18, through the pinions 13and ring gears associated therewith. f

Formingl a partof the h'ousing'16- are lateral plates 23 that are bolted to the housying section16 bymeans of lbolts 24. Formed in each of the plates 23 is a groove 25 which grooves accommodate spring members 26 that exert a constant pressure on the packing members 27 that contact with the shaft associated therewith to yprovide a fluid-tight connection between the housing and shafts permitting` the pinions 13 and lring gearsll and 21 to operate submerged in oil.

Supported on the drive shaft 18 is a pulley 28 over which'may operate a suitable belt notshown, for taking 01TV power from the drive shaft rand as shown, this pulley is formed with clutch flange 29 against which the clutch bandA 30 moves to rotate thepul-` ley 28 withfthe drivel shaft. The clutch band 30 is supported by sleeve 31 lkeyed to movement with frespect to the shaft-36h51 `means of the ball and socket joint 37 so that vmovement of the shaft A36 will result in a vrelative movementof the crank arm 33.

Secured to the crank arm 33 is a relatively short arm 38 that connects with the turn buckle 39 which in turn has connection with one end of the'clutch band 30 as at 40.

The vshaft 36 extends through a lug 41l formed on the movable sleeve 42, which movable sleeve is controlled by the `movement ofthe rocker arm 43 which is pivotally sup# ported by means of Jche threaded rod44 that extends through the support v'Tand secured thereto 'by means of the nuts 45.V "Thus .it will be seen thatby. adjusting the nuts 45 the movement of the arm "43 .may be regulated. *A recessedportion 46 is formed eirteriorly of the housing 16 and is lof a width brake bands within the recessed portion 46.'.

One end of the shaft 49 has connection with the lever 51 that has pivotal connection with the lug 52, formed at they opposite end of the brake band, through the shaft 53. the shaft 53 also providing asupport for the arm 54 mounted onone end of the vshaft 55 that an-k chors. one end ofthe brake band against movement.4 A Y Y Connectedy with one end of the link 51 1s a connecting'rod 57 which is connected to the bell crank lever 57 mounted on shaft 58 that is supported in the bearing 58 extending upwardly from the supporting member 62. D The arm 60 of the beller-ank lever 57 carries a roller 56 at its free end, which roller alsomoves in the opening 59.

The opening59 is formed with an offset portion 59 to cause the bell crank lever to rock, when'the'carriage 61 is moved longitudinally lof the support 62 whereupon the connectingrod 57 is moved, which in turn moves thelever 51 causing the brake band 47 to closely engage the housing.

The carriage 61includes a plate 63having its side edges mounted in the guideways 63 of the support 62, whichplate is also provided with .an elongated opening 64A h aving an offset portion 65 designed to move the arm 66 when thek roller 67 mountedvon shaft 68 and carried bythe arm 66, moves throughout the length of the elongated openne 64M The arm 66 is pivotally supported under the 'carriage 61at 69;.andvhas its forward end connectedA with theoperating rod 70 at 71. As' clearly shown by Figure 1 of the drawings, this rod 70 has'connection with the arm 43 at 72, to rock the arm 43.

Connected with the carriage 61 is a controlling rod 73, which, whenl moved by the operatoroperates to actuate the brake bands. The plate 63 has its side edges mounted in the lgroves 74 as clearly shown by Figure 1 of the drawings, whereby the plate may move freely upon the operationofthel rod 73. The operation of the device is as follows:

Assuming thatthe pulley 2S is 'moving in the direction of the arrow in Figure 1 ofthe 1 drawings, itis obvious/that. the drive is direct through the ring gear 11, pinions 13, ring gea-r 21 toit-he shaft 18 of which the pulleyforms a part. lVhile the gearing is operating as described, Ait is obvious that the housing 16 is stopped, the clutch bands hav- Y ing been operated to closely engage the housing. Should itfbe desired to reverse' the direction of rotation ofthe pulley 28, the rod 73 is forced'outwardly by a lever not shown,

whereupon the roller 56 moves in the lstraight portion of the elongated opening 59, holding the bell crank lever and shaft 57 or 57 against movement. y v t Simultaneously with the movement of the carriage 61, the roller 67 moves in the opening 64 formed in the plate 63 resulting in a l transverse movement ofthe operating rod 70 which in turn operates the arm 43 to move the collar 42 which in turn has connection with the clutch band 30 through the crank arm 33, thereby operating the clutch band associated therewith to cause rotation of vthe" pulley in the same direction as the rotation of the shaft 5. v f

Vhile the housing 16 is Vheld by the brake band 47, it is obvious that the rotation of' the shaft 9 rotates they pinions 13 on their shafts, which in turn rotate the ring gear 21 in a direction opposite to the direction of rotation of the ring gear 11 supported at the inner end of the shaft 9.

What is claimed as new is 1. In a device of the character described,

a. rotatable housing, a brake band associated with the housing to restrict movement of the` adapted to move in the second mentionedv elongated opening, the opposite end of the bell crank lever having connection `withthe brake band to operate the brake band when the plate is moved, and al clutch operating` .member operating in the first mentioned elongated opening, and a clutch operated by the clutch operating member, said clutch being operated simultaneously with the action of the brake.

2. In a device of the character described, a rotatable housing, a brake band associated with the housing to restrict movement of the housing, a shaft on which the rotatable housing operates, a sliding pla-te operating under the housing, means connected with the brake band and operated by movement of the plate for moving the brake band into rand out of operation, a clutch vmechanism, a rod for operating the clutch mechanism, said rod extending at right angles to the line of vmovement of the plate, means for connecting the plate and rod,`A and said plate adapted to opera'te to move ythe rod laterally when the plate is moved to operate the brake band.

In testimony that I claim the foregoing as my own, I have hereto aiii'Xed'my siUnat-ure.V
